This commit introduces KwActor with the full message surface and the immediate-reply contract for Start requests. The skeleton refuses unimplemented starts instantly, exposes idle status over a watch channel, and already routes RecordApply and GetReadiness through the shared history store and probes. This commit is part of the kw integration's step 4. Signed-off-by: lorenzoberts <lorenzobs@usp.br>
This commit makes StartBuild accept a job without waiting for it to finish. A detached task owns the process, broadcasts Idle to a terminal status, and cancel or shutdown kill the process group so the actor never wedges on a live job. This commit is part of the kw integration's step 4. Signed-off-by: lorenzoberts <lorenzobs@usp.br>
This commit spawns KwActor at startup and moves apply-history writes onto KwHandle so recording serializes with job state inside the actor. The handle is optional because the process module is unix-only; non-unix builds keep writing the store directly. Shutdown follows InputActor so a running job's process group is killed before the runtime tears down. This commit is part of the kw integration's step 4. Signed-off-by: lorenzoberts <lorenzobs@usp.br>
This commit makes Shutdown wait until kill escalation finishes, so tearing down the runtime cannot orphan kw's process group. Cancel escalates from SIGTERM to SIGKILL, and a process that exits before the signal lands keeps its real outcome instead of being reported as cancelled. The pre-job branch is recorded at accept time so RestorePreviousBranch has a target. This commit is part of the kw integration's step 4. Signed-off-by: lorenzoberts <lorenzobs@usp.br>
…spawn This commit maps a post-cancel reap by whether the process was signal-terminated, so a build that exits on its own keeps its real outcome. The pre-job branch probe moves above spawn so it records the branch from before the job starts, not from after the process is already running. This commit completes the kw integration's step 4. Signed-off-by: lorenzoberts <lorenzobs@usp.br>
This commit drops plan citations and comments about KwOps, checkout, and deploy that this skeleton does not implement. StartDeploy still replies NotImplemented; the comment now says that. This commit is part of the kw integration's step 4. Signed-off-by: lorenzoberts <lorenzobs@usp.br> Co-authored-by: Cursor <cursoragent@cursor.com>
